[Live-devel] Crash in AdvancedHashTable::keyMatches

[Marlon Reid]

Hi Ross,
 
I built a small application based on your testRTSPClient for multiple
streams
(http://www.live555.com/liveMedia/doxygen/html/testRTSPClient_8cpp-sourc
e.html).  I am however experiencing a problem that my application
crashes in AdvacnedHashTable::keyMatches because key2 is NULL.  This
happens after trying to create a media sink. I have compared my program
with the testRTSPClient and they seem very similar.  The major
difference is that I am using a FileSink instead of the dummy sink found
in the test program.
 
I will appreciate any assistance in tracking down the cause of this
problem.  I attach the callstack.  Thank you
